Gross Anatomical Study on the Pelvic girdle of Domestic Duck (Anas platyrhynchos domesticus)

摘要

In present study, one pelvic girdle was utilized. Pelvic girdle was composed of two hip bones. Each hip bone consisted of ilium, ischium and pubis. Ilium was elongated bone and attached with the synsacrum. Ilium was divided into pre actetubular and post acetabular part. Pre acetabular part was dorsally concave and contained cranial and caudal iliac crest. Internal surface of ileum contained renal fossa. Ilium and ischium form acetabulum. Acetabulum had articular area and perforation. Caudodorsal aspect of the acetabulum antitrochanter was situated. Obturator foramen was found caudal to the acetabulum. The size of the obturator foramen was smaller than the acetabulum. Caudal to the antitrochanter an elongated oval iloischiatic foramen was found. Ischium was plate like bone and it contained one pair of caudal process. Pubis was thin rod like bone and there was no symphysis between the pubic bone. Cranially pubis contained pectinal process and caudally it was curved. Between the dorsal border of pubisand ventral border of ischium incisura puboischiadica was observed.
